Patented July 24, 1934 UNITED 'STATES 1,967,213 y coNvEYEa LOADING DEVICE Viktor Beplate, Sydowsaue, near Stettin, Germany, assignor to North American Rayon Corporation, New York, N. Y., a corporation of Delaware Application August 18, 1931, Serial No. 557,922 In Germany August 18, 1930 10 Claims. (Cl. 198--20) 'I'his invention relates to a loading device for conveyers, but primarily has for its object to devise a means whereby the articles to be conveyed are transferred from one type of conveyer to another type.

In the manufacture of certain products, such as artificial silk for example, it is necessary that the articles of manufacture be given certain treatments or carried through certain manufacturing operations. In one of the steps of the process, one type of conveyer may operate in a certain way for moving the articles to be conveyed along a horizontal path, and in the next step of the process it will be found necessary to transfer the articles to' a conveyer which acts to raise and lower the articles through a treating tank, dryer, etc.

It is therefore the purpose of this invention to provide a loading device whichy is particularly adapted for handling of skeins or yarn bodies of artificial silk. In the manufacture of artificialsilk different treating steps must be carried out and certain of these steps are productive of better results if done by a dripping process, whereas others are better performed byl a dippingprocess. This of course makes it necessary to use different types of conveyers for transporting the skeins.

It is therefore one object of the invention to provide a novel and useful transfer device between the dierent conveyers used whereby there will be no delay in the conveyance of the transported" skeins or other articles. l

Another obiect of this invention is to connect the two mechanisms directly to each other by supporting devices which will automaticallyremove a carrier rod from one mechanism and transfer it to the other.

Afurther object of this invention is to' provide lever means secured to one mechanism, which, when a carrier rod is placed thereon, will automatically move so as to align the carrier rod with y mechanism before a carrier stick has been placed in position; and

Figure 4 is a similar view, but showing the operation of the transfer mechanism with the carrier stick in alignment with the conveyer belt or chain.

Referring now more particularly to the drawings, there is shown a dipping tank 10 mounted on suitable supports 11. Within the tank is arranged the usual system of conveyer rollers 12 over which passes the transporting belt or chain and which supports at spaced intervals, carrier sticks 14 loaded with skeins 15. The tank is also provided with an overflow pipe 16, having the usual valve 17.

A frame or. supporting structure 18 is positioned about the tank and is suitably spaced therefrom. Thetop 19 of the frame or supporting structure is provided with bearings 20 for shafts 21 which have secured thereto conveyer rollers 22; Lower conveyer rollers 23 are secured in position directly below the rollers 22. The conveyer is in the form of an endless belt or chain and is arranged on the lrollers to carry the skein carriers through the treating liquid as is clearly shown in Figures 3 and 4, the direction of movement being indicated by the arrows.

Means are provided to transfer the skein'carriers from the dripping to the dipping bath, and comprise levers 24 pivotally mounted on `the fixed machine frame 25 by any suitab`e means such as bolts 26. Each lever is weighted at one end and is provided at the other end with a cut out portion or groove 27. Thus the levers are normally in an upright vertical position as is shown by Figure 3.

The nonveyer belt is provided at suitable inter vals with pairs of hooks 29, adapted to receivey the skein carriers. These hooks consist of levers 30 pivotally secured to the conveyer chain or belt,

and each havinga claw like' member 31 secured at one end and a counter-weight 32 at the other end.

The operation of the ldevice is as follows:

The skein carriers 14 are led through a drip mechanism and are then placed in thev grooves 27. The weight thereof causes the arms 24 to swing over into alignment with the conveyer belt. The means 33 which place theI carriers in the grooves and the means which operates the conveyer areoperated either from a common driving means or by independent means. In either event the two are operated in timed relation so that when the arm swings over, the claw 31 is A stop means 28 is also provided at the vweighted end.

in position to receive the skeinlor cake carrier.

rial,

suitable means (not shown). On the top half of its path it carries the skein carriers 14 up and over and rests them in the grooves 27 of the anns 24. The rack means 33 continues down and back in its circular path and on rising, repeats the operation by picking up another skein carrier 14 which has been progressively moved along until it reaches the point occupied by the rst mentioned skein carrier 14, it then picks up the succeeding carrier 14 and deposits it in the by then vacated groove 27 of the arm 24 where it,

in turn is picked up by the hooks 29 on the conveyer belt. 'Ihe upward movement of the chain lifts the carrier from the groove 27 and the arm 24 is then swung back into position by means of the Weighted endto receive another carrier.

It will be readily appreciated that by the above arrangement there is provided a simple eicient and economical means of automatically transferring the skein and yarn carriers from a drip mechanism 'to a dip mechanism, thus obviating any handling of the product during the -wet treatment.

The mechanism may be varied in many respects without departing from the terms or spirit of the invention. f

Having now described the invention what is claimed is:

1. A mechanism for loading skein carrier rods on a conveyer comprising a support, a plurality of members pivotally secured thereto and suspended normally in a vertical position, said members swinging into the path of said conveyer when the said rods are placed thereon, whereby the rods are transferred to said conveyer upon movement thereof past the members.

2.' A mechanism for transferring skein carrier rods to an endless conveyer having spaced receiving means secured thereto comprising a frame, transfer members pivotally secured thereto normally suspended in a vertical position and swinginginto the path of said conveyer when skein carrier rods are placed thereon, whereby the said rods will be veyer upon movement past the transfer members.

3. A mechanism for transferring skein carner rods to an endless conveyer means having spaced receiving means secured thereto, comprising a frame, transfer members pivotally secured thereto, each member having one end formed with a recess and weighted at the other end whereby each member' is normally held in vertical position, said transfer members swinging into the path of said conveyer when skein carrier rods are insaid recesses, whereby the said rods 'will be transferred to said receiving means upon movement of the conveyer past the transferring means'.
